This pre-main amplifier inherits the digital support concept of the PM-84 and is refined by inheriting the AVSS.
Equipped with AVSS (Auto Voltage Shift Supply) that shifts the output supply voltage according to the power. By driving the power element at the output supply voltage most suitable for each power from small output to maximum output, high power is realized while maintaining the quality.
Designed for low impedance, it maintains power even when the speaker impedance momentarily fluctuates to an extremely low value.
Equipped with a direct switch, you can jump the tone amplifier and subsonic filter to feed the digital source directly to the power amplifier.
As a result, the signal path becomes the shortest path between the selector, volume, and power amplifier, enabling more pure playback.
In addition to the MM input, an MC input is also installed for playing analog discs.
There was a side wood sold separately.
